Whats the role of Kupffer cells in non-alcoholic steatohepatitis?
Nonalcoholic steatohepatitis (NASH) is a disorder characterized by hepatic steatosis, inflammation and fibrosis with a risk of developing cirrhosis and hepatocellular carcinoma (HCC). The progression from simple steatosis to cirrhosis has been attributed to inflammatory cytokines such as tumor necrosis factor alpha (TNF- ), oxidative stress and endotoxin, in combination with fatty degeneration due to insulin resistance. At present, histopathological examination of liver biopsy tissue is the only way to definitively diagnose NASH. The diagnosis of NASH is important in clinical hepatology, as this common disease is known to progress to hepatic cirrhosis and finally HCC. A research article to be published on October 21, 2008 in the World Journal of Gastroenterology addresses this question. The research team was led by Tatsuhiro Tsujimoto from Nara Medical University of Japan. Kupffer cells and hepatic sinusoidal function can be evaluated using the contrast effect in the liver parenchymal
